Claims (3)

1. Permanentmagnet-Gleichstrom-Elektromotor mit einem dosenartigen Motorgehäuse (5), einer in dem Gehäuse montierten Permanentmagneteinrichtung (18), einem gewickelten Anker (3) und einem Kommutator (4) an einer Motorwelle (2), die drehbar in dem Motorgehäuse gelagert ist, Kommutatorfahnen (23) zwischen dem Anker (3) und dem Kommutator (4) für den elektrischen Anschluß der Drähte der Spulen des Ankers (5) an den Kommutator (4) und mit einer Endkappe (10), die das Motorgehäuse verschließt und einen Bürstenstromabnehmer (14) hält, dessen zugehörige Bürsten mit dem Kommutator in Kontakt stehen, gekennzeichnet durch ein Zentrifugalgebläse (24), das über der Motorwelle zwischen dem Anker und den Bürsten angeordnet ist, und zwischen dem Anker und den Bürsten in dem Motorgehäuse ausgebildete Fenster (22), wobei das Gebläse eine Vielzahl von Flügeln (26;26') aufweist, die einstückig mit einer ringförmigen Flügelhalterung (25,27;25',27') ausgebildet sind, die eine Ansaugöffnung des Gebläses definiert, wobei die Flügel (26,26') sich über den Kommutatorfahnen (23) erstrecken und die Halterung (25,27;25',27') an dem dem Kommutator nächstgelegenen Ende des Ankers und in einer Position angrenzend an die äußere Umfangsfläche des Ankers festgelegt sind, wodurch von beiden axialen Seiten her Luft zur Kühlung des Kommutators (4) und des Ankers (5) in die Ansaugöffnung gesaugt wird.
2. Elektromotor nach Anspruch 1, dadurch gekennzeichnet, daß die ringförmige Flügelhalterung eine zylinderförmige Wand (27;27') und eine ringförmige Flügelverstärkungsplatte (26;25') aufweist, die sich radial ausgehend von dem Wandende erstreckt, das von dem Anker entfernt liegt.
3. Elektromotor nach Anspruch 1 oder 2, gekennzeichnet durch ein Gebläse-Montageelement (40), das mit dem Anker verbunden ist, wobei das Gebläse und das Gebläse-Montageelement komplementäre Ausbildungen (46,47) aufweisen, durch welche das Gebläse durch Schnappverbindung in das Gebläse-Montageelement eingerastet ist.
